Be aware that plastic sleeving can degrade depending on how long the instruments will be in the SFP and the proximity to the fuel. For short term exposure, this is generally not an issue.
I've seen both good application of sleeving and some bad (Leaks) Fred From: [email protected] [mailto:[email protected]] On Behalf Of Thomson, Raymond W.

Simple strippable coatings have been used with some success as well as plastic sleeving. Are you working with companies that design and market underwater detectors? I'm assuming radiation detectors or are these thermocouple/level indicators...?

We would like them returned to us with as little contamination as possible. What does your plant do to reduce contamination in items placed in the spent fuel pool? Any advice is appreciated!
